CONTAINER Application am A ril 8, 1929. Serial No. 358,480.

My invention relates to containers and refers particularly to containers having a plurality of chambers.

\Vithout limiting my device to such use, it

6 is designed particularly for use with a plurality of chemicals, the combination of which in the presence of water will cause a decided reduction in temperature in the vresulting mixture.

It is frequently desirable to cool a liquid Without the direct introduction of ice, thus avoiding a dilution of the liquid and the introduction of such objectionable products as may be contained in the ice.

1 This is usually accomplished by inserting a container containing the cooling ingredients into the liquid to be cooled, the temperature of the cooling mixture being transmitted to the liquid to be cooled through the walls of the inserted container.

While ice may be employedas the cooling medium, it is sometimes desirable to have some other cooling medium, such as a mixture of chemicals which through their chemi- 95 cal reactions cause a reduction in temperature.

As this means of cooling is a chemical reaction, its success depends upon the chemicals employed, the quantities of those chemicals and the amount of water necessary to accomplish the .proper reaction.

It is evident, therefore, that if such chemicals are to be sold to the general public for this purpose, the chemicals and the amount of each such chemical and the amount of water should be clearly indicated to those who wish to employ them, and my device accomplishes all of these desirable results.

, The device of my invention comprises a m carton, or container, having a plurality of chambers therein, said chambers being formed by moisture-proof partition, as of parafiin, at least one ofsaid chambers being lined with a water-proof material.

i A further feature of my device is that each of the compartmentsof such size and capacity to hold the necessary amount of one of the ingredients, the water-proof lined compartment being of such capacity to hold the 9 necessary amount of water.

My invention thus presents a single carton containing the proper amount of chemicals and acting as a measure for the proper amount of water.

In the accompanying drawings, illustrating one form of the device of my invention, similar parts are designated by similar numerals:

Figure 1 is a vertical cross-section of one form of my device. (it

' Figure 2 is an enlarged vertical cross section of the partition portion of my device.

Figure 3 is a section through the line 33 of F1gure 2.

The particular form of the device of my a: invention, shown in the accompanying drawings, comprises an outer annular casing 10 within one portion of which is an inner annular casing 11 0 en at both ends and having an annular shoulder 12.

An annular paraffin partition 13 extends across and covers one open end of the inner casing 11 and extends downwardly into the recess 1% formed by the inner extremity of the inner casing 11 and the outer casing 10.

The inner casing 11 has a paraflin paper lining 15.

The caps 16 and 17 act as closures for the two open ends of the outer casing.

The operation of the device is as follows":

The caps 16 and17 are removed and'the chemicals 18 and 19 are introduced into a container within which the cooling liquid is desired. The upper portion of the device which is paraffin lined is then filled with water which is then added to the mixture of chemicals 18 and 19, the proportion of water and chemicals being such as to produce the minimum temperature.

I t will thus be seen that my invention is a hermetically sealed device preventing the admixture of the two chemicals, one of the chambers of the device acting as a measure for the required amount of water necessary for the proper reaction between the chemicals.

lVhile I prefer to have the casings made of cardboard and the partition of parafiin, my invention is not limited to these two materials and the device may be a different size and shape and of different arrangement of parts, those shown being given simply as a means for clearly explaining my invention.

\Vhat I claim is 1. In a container, in combination, an exterior casing open at both ends, an interior casing open at both ends and of less len h than the exterior casing, said interior casing having a shoulder at its interior end portion forming a recess between the exterior casing and interior casing, a water-proof partition closing the inner end of the interior casing and extending into said recess and a closure for each end of the device.

2. In a container, in combination, an exterior casing open at both ends, an interior casing open at both ends and of less length than the exterior casing, said interior casing having a shoulder at its interior end portion forming a recess between the exterior casing and the interior casing, a water-proof partition closing the inner end of the interior casing and extending into said recess a waterproof lining for said inner casing, and a closure for each end of the device.

Signed at New York city in the county of New York and State of New York this 3rd day of April, 1929.
